CANADA.

Specification of Letters Patent.

Patented sept. V5, 1.911.

Application filed March 7, 1911. Serial No. 612,734.

To all whom it may concern:

Be it known that we, WALTER U. APPLE.

TON and GEORGE E. MoCoY, subjects of the King of Great Britain, residing at Moncton, in the Province of NewBrunswick, Dominion of Canada, have invented new and useful Improvements in Apparatus for Removing and Replacing Car-Wheels, of which the following is a specification.,

This invention relates to apparatus for removing and replacing car and locomotive wheels or similar heavy bodies, the obj ect of the invention being to provide means whereby the wheels may be quickly removed from the car body or truck and repaired or new wheels substituted without necessitating the removal of rail sections of the track on which the car is mounted..

Another object of the invent-ion is to provide in said apparatus a portable truck adapted to be moved vertically and carrying rail sections adapted to form a portion of the shop track on which the car to be repaired is mounted to travel; furthermore, the provision of a pit in which the truck is adapted to travel after it has received the wheels, and further, the provision of a lifting and lowering mechanism operating to move the truck vertically to receiving position and to lower the truckv to discharge position, and the construction of the truck and the said raising and lowering mechanism, whereby they are detachably connected with each other so as to permit the truck to be readily and freely moved in the pit after the lowered position of the lowering and lifting mechanism.

Another object of the invention is to provide novel locking mechanism operating to hold the truck in an elevated position, whereby the rails of the truck `form a continuous part of the shop track so as to permit of the passage of the rollingv stock over the truck rails when the truck isnot used for the purpose to which it is primarily intended.

Another object is to provide eHicient means for vertically guiding the truck to its work and for insuring accuracy in alining the truck rails with the permanent track rails.

In the drawings, forming a ortion of this specification and in which like numerals of reference indicate similar parts in the several views z-Figure 1 is a vertical section through our improved apparatus showing the truck in full lines with respect to the car wheels to be removed and showing in dotted lines its lowered position. Fig. 2 is a vertical section on the line 2--2 of Fig. 1. Fig. 3 is a plan view vof the sameI with parts in section. Fig. 4 is a side view of the supporting bracket for one of the locking elements. Fig. 5 is a section on line 5 5 of Fig. 4. Fig. 6 is a sectionon line 6 6 of Fig. 4. Fig. 7 isa plan view of the truck, the wheels 'thereof being removed. Fig. 8 is a side view thereof. Fig. 9 is an end view of the same. Fig. 10 is a section through one of the truck wheels. Fig. 1l is a plan viewof a portion of one of the truck wheels.

The apparatus includes a pit l which is formed in the ground or in the shop beneath the track structure on which the rolling stock is adapted to travel, the pit in the present instance being preferably constructedof concrete or the like and being formed so as to provide a longitudinally extending passageway 2 which extends' transversely tothe plane of the rails 3 of the shop track structure, the pit opening vertically at one end directly between the rails 3 for a purpose to be hereinafter described.

A truckl4 for the transportation of the car wheels is designed to travel vertically andhorizontally in the pit, and as illustrated, the truck embodies a base plate 5 on which the longitudinally extending eye beams 6 are secured. Rail rest supporting plates 7 are suitably secured to the I beams 6 near the ends thereof, each plate having mounted thereon a rail section 8. Braces 9 are secured to the base plate 5 and they are formed to provide branch portions 10 which are 'secured in any well known manner to the upper flanges of the I beams 6, as clearly -shown in- Fig. 9 of the drawings. Similar braces 11 extend outwardly from the base plate 5 and are secured to the ends of the rails 8 and to guide blocks l2 at the ends of the rails beneath the rails, as shown. The truck is provided with a pair of axles 13,'.each having identically constructed fiat head portions 14 fixedly secured to the uni derside of the base plate 5. The spindle ortions of the axles extend outwardly rom the heads 14 for the reception of the wheels '16, each wheel being identical in construcl is formed with a threadedl extremity 21-to which istted a retaining nut 22.and 'it washer 23, the latter frictionally bearing against a washer 24 in one side of the hub when the retaining nut is in its adjusted position. The ends of the rails 8 extend beyond the sides of the truck so that the guide blocks `12 may be operatively positioned in guides 25 which are arranged vertically in the pit and transversely to the plane of-the rails 3 forming theshop track structure.

The guides 25 are preferably formed in brackets 26, each comprising a vertical plate which is substantially coextensive in height with the depth of the opening of the pit, beingformed with spaced vertical walls 27 and 28, the latter having its major portion oset from the wall 27 and formed extended through the lower reduced end of to provide an ear 29. The ear of each bracket supports'a bearing pin 30 which is l'a locking element 31. Similar pins 32 extend through the locking element and through arcuate slots 33 in the brackets. The brackets are arranged, preferably, in pairs, two pairs being shown in the present instance, and as shown, the locking elements of each pair of guide brackets are adapted to be simultaneously moved through the provision of a' controlling mechanism. This mechanism preferably comprises a rock lever 34 which is mounted on the bearing pin 35 whichis supported on the bracket shown at the right in Fig. 1 of the drawings. At one end, the rock lever is pivotally connected to the locking element through the link 36. At the opposite end, the rock lever is connected by a link 37 to the locking element 31'shown atl the left in Fig. lof the drawings. Thelocking ele-- The bottom wall of the pit has suitably mounted thereon a track structure embodyingv parallel spaced rails 40 which extend substantially the full length of the p1t. These rails are so spaced from each other as to permit the truck 4 to travel thereon in a. manner to be'hereinafter described. A

Raising and lowering mechanism is em- .ployed for moving the truck 4 vertically in the pit. This mechanism, as herein shown, comprises a iui'd cylinder 41 which 1s mounted in any suitable manner 1n the bottom of the pit. The cylinder is provided with a relatively long vertically sliding piston 42, the lower end being closed by a head 43 in which is fitted a pluo 44. The plug 'is provided with a depending portion 45 which extends below the plane of the head 43 and which is adapted to contact with an upwardly extending contacting portion 46 on the plug 47 in the bottom of the cylinder. The portions 45 and 46 when in contacting engagement serve to hold the bottom of the piston spaced from the bottom of the liuid cylinder so as to provide for the effective intro'duction of the fluid into the cylinder and beneath the piston. A conduit 4S is connected at one end Vwith the iuid cylinder near the bottom thereof. This conduit may be arranged in communication with any suitable source of supply, such as .steam or air. In either instance the conduit may be provided with any suitable well known form of controllingl valve to permit of the introduction of the fluid to the cylinder or the exhausting of the fluid therefrom as the occasion may demand. At the upper end, the piston is closed by a cap 49. This cap is provided with a head 50 onwhich is formed an upwardly extending boss or lug 51 which is designed to tit in a correspondingly formed passage 52 in the base plate of the truck 4.

In operation of the apparatus herein speciieally described,l it can be stated that when it is desired to move the truck 4 upwardly in a receiving position with respect to the wheels of the car to be removed the truck is moved longitudinally on the track in the bottom of the pit to a position where the opening 52 in the base plate will'receive the boss or projection l51 on the head 50 of the piston cap 49. The introduction of Huid to the cylinder 41 will operate to move the piston 42 in an upward direction so as to carry therewith the truck 4. After the truck has been adjusted to its full elevated position the rails 8 thereon will be in exact alinement with the rails 3 forming the permanent track structure. The guides 25 will operate to retain the rails 8 in alinement with lthe rails 3. l

After the piston 42 has been raised for the purpose above named, the motive fiuid may be cut oli and the levers 39 may be operated so as to move the locking elements beneath the guide blocks 12 onthe truck.

When the locking elements are in locked positions they are arranged at an angle with respect to their supporting brackets, the supporting surfaces 52 of the said locking elements being inclined downwardly from the top of the pit and having effective contact. with the correspondingly downwardly inclined contacting surfaces 53 on the bottom of the guide blocks. When the locking elements are in their released positions they are disposed vertically with respect to their supporting brackets and they are extended into the offset portions in the walls 28 of the brackets so as to lie out of the path of movement of the guide blocks so as to not interfere with the movement of the truck and plunger respectively during the lowering operation. After the wheels of the locomotive or carv are disposed immediately above and operatively associated with the rails 8 on the truck 4 the fastenings on the car truck are removed from the axle so as to' permit the axle to be lowered with the wheels on the downward movement of the truck 4. When the truck 4 is down in the pit to the full limit of its movement the wheels 16V of the truck will be operatively associated with the rails 40 in the bottom of the pit. When the piston is down in the fluid cylinder to the full extent of its movement the projection 51 on'the cap 49 will not desired to use the truck 4 for the pur-l pose primarily intended herein t-he truck may be raised to a position where the rails thereof will aline with the rails 3 so that the rails 8 will form therewith a continuous porti-on of the shop track. At this time the locking elements 31 are operatively engaged with the guide blocks ofthe truck4 so as to hold the truck against downward movement in the pit.

While the mechanism illustrated herein includes means for moving the truck vertically, it is obvious that the pit can be so constructed that the truck can be moved horizontally to a position where the vtrack section of the pit will close the gap in the permanent track structure, the said gap being formed through the omission ofsections or portions of the rails of the said permanent track structure.
